To all whom it may; concern lde it known that lh Tn s citizen of the United States re.)

ngnian, in the cou nines; a hug at ,i itate oiilndiana. haveinvented a new and useful improvement in Tro ev-Fllwel llllounts of which the iollowinu; lication My invention relates to that class oi? trolley-Wheel mounts wherein a substantial mount is provided whereby a trolley-wheel supported in hearings and upon the extrenie end oil? a trolley-pole and Withparticular reference to the trolley-wheel mount is a speci described in Letters Patent lilo. 1,142,846, issued to this applicant under date of June 15, 1915Qentitled 'llrollevavheel ruountsi And the objects oi? my invention are; first, to provide a suitable bearing; and support tor a trollevwheel upon the extreme end of a trolley-pole; second to provide such a device Which by reason or its peculiar struc ture and attachments, permits an automatic adjustment in the position of: the trolley a curve in the trolley- Wircu for the purpose or avoiding); the danger of the trolley-Wheel jurriping the Wire; and third, to provide such. a device which will be substantital 'sightl'y, sate from dis placement andv oi economical construction.

These objects l". attain by means of the device illustrated. in the accompanying; drawings in Whichz- Figure 1., is a side elevation of the device.

Figure 2, is a view oi the front edge of the device.

Figure 3, is a vertical sectional view of the device cut through the axis oi the tro lley-WheeL I Eiimilar letters and niunlerals ct reference refer to similar parts throughout the several views.

The numeral. 22; indicates a trollevavheel of the usual sheave-Wheel type, provided with a hollow huh 3, which is rotatably mounted upon a shaft l.

The shaft .lis perforated to form an oil- Wheel While passin vent 5, Which extends from the center oi" one end to near the nuddle of the shait and then and a head-stock 7.

the searing-arms 9. The bearingt each, providedwith outwardly pro ecting and hes/oiled hub-like journals i which are perforated centrally, to ree and support the ends for the shaft l.

' sins ll translix said journals 10 and the seals 4, thereby holding said shait stationary.

The base 51% is squared and proportioned to hit ,looselv upon the top of the head-stock 7, and is 'iertorated verticallyand centrally to receive the head-p 12. The base is thickened to form a substantial bearing for the hea -post l2, and is perforated to term an oilsvent l whereby lubricant is fed to the bearing; and head-post. The upper end or? the head-post 19% is perforated to receive a cotter-pin 1e, and a Washer 15, takes up play between said eotter pin 14land the base 8.

Ublongr slots 16 are test in the sides of the beariugarms 9; and strong brasssprings it which are attached to the outer surtahe arms 9 oi the bearing-arms 6, by screws l8,pass' permit the passage therethrouoh, of the shatt 41 oi? the trolley-Wheel.

When so mounted the springs 1.7 serve as friction Washers between the ends of the trolley-wheel hub and the inner faces of the corresponding; bearinnaarnis, and at the same time serve to hold the trolley-Wheel jtirniily in normal. position Recessed shoulders 19 are cut into the extreme lower edges of the two sides of: the trolley-head tor the 1:1urpose hereinafter set liorth.

'llhe head-stock '5' consists oi substantial metallic body, enlarged and squared. at the top and tapering; downward to a ferrulelilre shank 920; the lower end of said shank is hollow and adapted to receive the extreme end oil a trolley-pole 21 upon which the heed-stock is mounted and fixed by a bolt 22. A. ring like projection. 23, projects from one side of the shank 20, for the purpose of attaching' a controlaope thereto.

The upper face of said head-stock 7, is squared and adapted to hold thereon the squared base oi the trollejv-head 6, and a head-post 12, projects upwardly from the center of the upper face of headstock, and passes through the perforation in the center of the base of the trolley-head. The said head-post is perforated horizontally near its upper end and carries therein a cotter-pin 14, which confines thereunder, a washer 15, which rests upon the base, and takes up all lost play between the trolley-head and head stock.

Strong flanges 24, project upwardly, from each edge of the two sides of the head-stock, and lap over upon the corresponding sides of the trolley-head opposite to the recessed shoulders 19, and are adapted to engage and stop the base of the trolley-head when the same is turned to either side, and thus prevent the trolley-head from. revolving too far, when the trolley-wheel is following a curved wire.

The advantages claimed for my improvement consist, first, in the substantial Structure and ease of assembling and dismounting the various members, whereby the removal of the worn or broken trolley-wheel and the substitution of new parts may be quickly and easily accomplished; second,

by reason of the peculiar union of the trolley-head and head-stock and the space provided between the recessed shoulders 19 of the trolley-head and the flanges 24 of the head-stock, a free revolving movement of the trolley-wheel is provided whereby the trolley-wheel is made free to follow a curving trolley-wire around corners and curves, without any strain or wear upon the wheel or members of the mount; and third, the substantial and light structure oi the mount renders the device economical, of long life, and attains a maximum of safety from displacement and incidental accidents.

\Vhat I claim asnew and useful, and desire to protect by Letters Patent, is:

1. The combination or a rotatable trolleyhead and trolley-wheel axle or shaft with a head-stock adapted to movably supportsaid trolley-head, a head-post integral with said head-stock, and adapted to confine said trolley-head in movable connection with said head-stock, upwardly projecting flanges upon the upper edges of the sides of said head-stock, adapted to lap over the sides oi? said trolley-head and to engage-and hold said trolley-head from excess movement, recessed shoulders cut into the lower edges of the sides of said trolley-head and opposite to the two corresponding flanges oi? the head stock adapted to providespace for limited revolution of said trolley-head; a pair of oppositely disposed springs attached to said trolley-head and adapted to bear upon opposite sides of the trolley-wheel, all substantially described and shown and for the purposes set forth.

2. In a trolley-wheel mount the combination oi a rotatable trolley-head, said trolleyhead consisting of a base and two bearingarms, journal bearings in said bearing-anus adapted to support the shaft, a trolley-wheel, a troilcy-wheel shaft, mounted in said journal bearings and adapted to support a trolley-wheel, means of firing said trolley-wheel shah; in said journal bearings. with a headstock adapted to support said trolley-head upon the upper ,i'are, a head'post integral with and upwardly projecting from said head-stock adapted to confine said trolleyhead in rotatable connection with the headstock, a pair of flanges projecting upwardly from said head-stock and upon opposite sides of said trolley-110ml and being ada nod to prevent excess movement of the tro levhead, recessed shoulders in the lower edges of the trolley-head, adapted to permit necessary movement of said trolley-wheel between said flanges oi? the head-stock, a pair oi? oppositely positioned springs attached to the sides of said trolley-head and ada ited to bear upon either side of the trolley-wheel. all substantially as described and shown and for the purposes set forth.

3. In a trolley-wheel mount, consisting of a rotatable trolley-head and a fixed ln-ad stock, in movable connection with each other. means of movably attaching said nienilwrs together, a pair of opposinp springs attached to said trolley-head and adapted to bear against the. sides of the trolley-wheel and to serve friction washers between said trolley-wheel and corresponding portions of said trolley-heath a shaft journaled in said trolley-head and adapted to support said trolleynvheel, a pair ol flanges upon the top oi said head-stock adapted to rcgnlate the rotation of said trolley-head. a hollow snanh integral with said laud-stock adapted to i'it upon the end of a trolley-pole. means of attachin said head-stock to said trolley-pole, all substantially as shown and described.
